IMPROVED METHOD OF SECURING 'lUSHES FUR BUNGS TQBARRELS.

Specification forming part of Letters Patent No. 47,87 7, datcil- May23, 1865.

To all whom it may concern;

Be it known that I, THOMAS SUMMERFIELD,

of the city and State of New York, have invented, made, and applied tousea certain new .and useful Improvement in Means for Securing Bushesfor Bungs in Barrels; and I do hereto be inserted into the staves ofbarrels; but

in consequence of being secured by rivets whose heads have been on theinner side of the stave the bnsheshave necessarily been inserted beforethe barrel was complete, or by taking out the heads of oldbarrels.Bushes of this character are found in Letters Patent granted June 9,1863, to Kenyon and A. Menzies. The naturevof my said invention consistsin a lever-anvil to be inserted through the metallic bush, which servesthe purpose of an anvil against which to clinch the ends of nails drivenin to secure the metal bush, and at the same time acts as a lever tohold the bush firmly to the barrel while the nails are being driven andclinched.

In the drawings, a represents part of the stave of a barrel; b, the bushfor the plug or bung; a, the flange of said bush, formed with holes forthe reception of the nails. and use four such holes.

f is my lever-anvil, formed of metal, with a fiat head, 9, at one endand agrooved head, 72, at the other, the metal shank or lever near theanvil at each end being bent, as shown, so that after the head or anvilhas been passed through the bush the anvil-head may be brought up nearlyflat against the inner side of the stave andthe lever bear upon theouter face of the bush, so as to be sustained by the press the bushfirmly down upon the stave. After the bush has been driven into'thebung-hole in the stave, the

grooved head 71. is first to be entered toslightly, turn up the-ends ofthe nails cl as they are driven. (See Fig. 1.) The holes may be bored inthe stave for said nails, if desired. The lever-anvil is then turned endfor end, so as to enter the flat head- 9, and this clinches the nails aseach nail in succession is driven firmly home by a/hammer struck uponits head. By this means the metallic bushes may be secured in barrels inthe most permanent mannerwithout the necessity of taking out the head,as

heretofore usual.

What I claim, ters Patent, wis
